I l I Reterring to the drawings and to the emlinY the use ot dry batteries, it is often bodiment ot my invention, which I have sefound that ivlien the battery is closely conan electric lamp having as a means of curmaterial olil which the battery is composed rent supply a4 battery 4., which in the present exudesm'lows about the sides of the battery instance a dry battery inclosed within a and dries or erystallizes, thus causing the ci'iiitaiiier in the torni ot' a casing 5, the battery to become' fastened to the sides or e'O latter being` herein of generally cylindrical internal walls of its container in such a shapiaiid `havingat one end an opening 6 manner that it is extremely difficult to ex- 95 tor ilu introduction and reiiioval. oit the battract ythe battery therefrom. This action is tcry. lu tl c presentinstancia this opening called freezing. Here'tolore when this has is closed by an appropriate closure 7 which taken place7 it haslbeen frequently necessary te niav he in thetoi'm ot a rotatable cap proto bore the batteries out oitI their containers i'idici'l with a f ircumterential bead 8 having because they have been frozenv in place so 10o thifrein an annular recess 9 tov receive one or badly. As ameans for preventing `such more.. herein two, projections l0 on the casfreezingf ot the battery to its casing7 l ing f3 whereby the cap is normally held in have herein provided for the-.circulation otl t its place on the casing but is permitted to `an1 about the top, sides and bottom ot the turn. battery. 'lo this end, the battery is herein los lfnlorder to provide lier the removal .ot the l separated from its casing' about its sides by cap, its hea@l 8 is herein provided with an an airspace i8, at its top by a chgamber 19, opening or notch ll. which when turned and at its bottoni bya chamber 2u. ln the form shown, there is interposed between the battery and its casing a double walled jacket or envelop 21of appropriate material, as for example, as heavy paper, the same being provided with a bottom 22.

It will be observed that the contact member or conductor 1.7, is interposed between the bottom or inner end of the battery and the bottom or inner end 22 of the inclosing jacket 21, whereby there is formed between 'the two an air space 23 which directly conr municates with the annular air space 1S about the circumference of the battery, and since. the circumferential air space directly communicates with the chamber 19 at the opposite end of the casing, ay complete air space is formeel about all sides of the battery.

As a means for admitting external vair to the described air space within the casing, the latter may be provided with one or more, herein a plurality, of perforations 24. These perforations will by preference be located in the bottom of the casing, so that while perniittingthe entrance of air, they will no t ad,- mit rain, if the casing be placedin an upright position as shown. This is a matter of considerable importance in case the lamp is used out of doors, as for example, on a vehicle. l

In order to provide for the entrance of external air into the air space within the en'- velop or jacket 21, the bottom 22 of the latter is likewise provided with one or more,I

herein a plurality, of perforations 25, establishing communication between the chambers 2O and 23. As a means for maintaining the chamber 20 and supporting the jacket 21, which contains the battery, in spaced relation withthe bottom of the casing and the perforation or perforations therein, the bottom of the casing is herein provided with a raised portion V2G, preferably centrally located. It will now be apparent that the described perforations provide for the entrance of external air to the casing and the air spaces about the battery provide for a complete circulation of such air, so that the tendency of the battery to become frozen to the walls of the container is practically nullified. The perforations, moreover, provide for the introduction of a suitable implement to push the battery out of its container whether or not frozen therein.

The metal of which the battery casing is formed is usually rather thin and to a certain extent likely to become distorted or collapse about the opening 6 through which the battery is introduced and removed. Such distortion ofthe casing, if permanent, would, of course, diminish to a considerable extent or close the air space between the battery and its casing, and would be apt to interfere with the circulation of air, as well as make it dicult to withdraw the battery from its casing. ln order to prevent such distortion. or collapse of the casing about its entrance,

I have herein provided strengthening means about the opening, preferably inthe form of a circumferential bead 2T, which lends -0 great strength to the (,ircumferential wall of the casingand makes the latter so strongthat there is no danger of its becomingdistorted with ordinary reasonable use, and the ,casing may even be subjected to considerable stress without likelihood of pinching the battery. The bead, moreover, lends such strength to the edge of the casing about the opening that the interengagement of the projections 10 with the annular recess 9 ranc not be interrupted in ordinary usage.

Thile I have herein shown and described one specific embodiment of my invention for illustrative purposes, and hate disclosed and discussed in detail theconstruction and arrangement incidental to one specific applilation thereof, it is to be understood that the invention is limited neither to the merev details or relative arrangement of parts, nor to its specific embodiment herein shown. but that extensive deviations from the illustratedform or embodiment of the invention may be made, without departing from the principles thereof.
